WATER-HEATER.

Specification of Letters Patent.

Patented Feb. 25, 1913.

To all whom it may concern:

Be it known that I, IVILLIAM CnoMwnLL GURNEY, of the city of Toronto, county of York, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Tater-Heaters; and I hereby declare that the following is a full, clear, and'exact description of the same.

The object of my invention is to devise a water heater for domestic or other purposes in which the water may be raised to the desired temperature in a short space of time, and to so construct the water heater, that ordinary use will not cause leakages at the joints of the heating coils and headers, this object being attained by the use of a flow header and a return header, and a set of heating coils connected therewith, the water headers being rigidly coupled together to prevent any change in their fixed relation to each other and to the heating coils.

For an understanding of the invention, reference is to be had to the following description and to the accompanying drawings, in which .Figure 1, is a front elevation of the heater; Fig. 2, is a broken side elevation of the same; Fig. 3, is a front elevation of the water headers and heating coils; Fig. 4, is a side elevation of the construction shown in Fig. 3; Fig. 5, is a vertical section on the line a-a Fig 3; and, Fig. (5, is a vertical section corresponding to Fig. showing a modification of the headers.

Like characters of reference refer to like parts throughout the specification and drawmgs.

In Figs. 3, 4: and 5, I have shown the water heater to consist of a return header a, and a flow header 6, rigidly connected by a web 0, a set of heating coils cl connected to the headers, and a web 0 rigidly connecting. the headers a and Z) together, to prevent their independent movement in any direction. The heating coils (Z are preferably made of copper tubes, bent to a serpentine shape and having their ends (Z d fitted to the headers a and b. The shape of the heating coils, however, is immaterial, and may be varied to correspond with the capacity of the heater and therefore I desire it to be understood that the term coil will include in its meaning a tube or pipe of any shape suitable for the requirements of the work of the user. For ordinary domestic purposes, I find that the heating coils, when made in a serpentine shape as shown in Figs. 4 and 5, heat the contents of any ordinary range boiler to boiling point in a comparatively short space of time and I have found that by actual test it is possible to raise the temperature of water in the flow header from about 32 Fahrenheit to 180 Fahrenheit in a space of forty seconds and that I can heat the contents of an ordinary bath tub, in fifteen minutes time from the lighting of the burner.

I11 the construction of the water heater, I preferably make the water headers a, and b and the webs c of a single casting, but it is possible to make the headers a and b separate from each other and to connect them together by a rigid coupler, such as shown in Fig. (5, the return header a and flow header 1) then being formed with flanges e, to which is bolted a metal plate f. To confine the heat around the heating coils, the latter and the How and return headers are incloscd in a suitable casing. This casing consists of a front g and two sides g, preferably formed of sheet metal, the sides 9, near their rear edges, being bolted to the flanges c of the web 0. The front 9 of the casing is apertured, and hinged to the sides of the front g is the door 9 to permit of access to the heating coils and burner 71.

When the burner is lighted the heated gases therefrom pass upward through and around the heating coils being deflected against them by the web 0 or its equivalent as shown in Figs. 5 and 6, and confined around them by the casing until the gases pass through the outlet 9 at the top of the casing.

Having thus fully described the nature of my invention, what I claim as new and desire to secure by Letters Patent, is 2- 1. A water heater comprising two headers situated one above the other, means integral with said headers to rigidly hold them immovable in their fixed relations to each other, a set of heating coils connected with said headers, and a burner situated below i ing coils, and a casing inclosing said headers, said heating coils. heating coils and burners. 10
